HERMANN L. BEHRENS, OF HOLYOKE, MASSACHUSETTS SELF-OILING CALENDER-BOX..

SPECIFICATION forming part of Letters Patent No. 282 ,151, dated July 31, 1883 Application filed Februaryfl, 1883. (No model.)

-To all whom it may concern:

Be it known that I, HERMANN L. BEIIRENS, of Holyoke, Hampdeu county, Massachusetts, have invented a new and useful Improvement in Self-Oiling Oalender-Boxes, of which the following is a specification, reference being had to the accompanying drawings, which are hereby made part thereof. 1

Figure I is an end elevation of a calenderstock. Fig. II isa plan view of my invention. Fig. III is a sectional elevation of same. Fig. IV is a side view of the-rod supporting the calender-boxes. Fig. V is an edge view of the same. Fig. VI is a longitudinal section of the oiling-cylinder. Fig. VII is a vertical section of the same.

Similar letters of reference indicate corresponding parts.

A is the rod for supporting the calender-' boxes. at is a bolt-slot inthe end of rod A. B is a calender-roll. bis a horn on the end of rod A opposite end from bolt-slot a. O is the oiling-cylinder. c is a pinhole in the end of horn b. D is a bracket supporting oiling-cylinder. E is the cheek-piece or bearing-piece in the calender-box, and is made of bronze. F is a set-screw for adjusting cheek-piece E. G is the intermediate calender-box. H is a bolt for fastening rod Ato intermediate calender-box, G. I is a thumb-screw for fastening K K are the top and bottom boxes of the calender-stock.

L is the frame of the calenderstock. M is the cap of the calender-frame. N is the screw lever. O is .the pressure-screw. S is the fill ing-tube for the oiling-cylinder. T T are journals of the oiling-cylinder. V VV V are the. holes in theoi'ling-cylinder through which the oil flows. X is a felt covering around the oiling-cylinder. Z is a lug on the lower'side of. the intermediate calender-box, having a hole,

Y, by which the rod A is attached to the calender-box by its horn b.

The calender-boxes and self-oilers are for intermediate rollers, and are not intended for driving or top rollers. The boxes are two halves, so as to have the journals open at the top and bottom, so that in case of the breakare worn out, they can be replaced without removing the rollers. The boxes are to hold the rollers from moving to either side. If the calenders are stopped quickly, the journals can move up or down without breaking the boxes. The self-oiler is made of a long roller, so as to oil the entire journal and collar at the same time. The oil is kept inside the roller, which is covered with flannel, so as not to fly over upon the paper,whieh occurs when the calenders are suddenlystopped. The oiler does not require to be movedwhen the boxes are taken out. A further object of the flannel is to keep the holes in the roller from filling up, and at the same time to hold the oil which flows through the holes through which the rolls are oiled. A further object in having the oil inside the roller is to avoid spilling or wasting any of the oil when the boxes are removed with the oiler attached.

The method of operation of my invention is as follows, to wit: The cylinder is filled with oil, and its resting on the journal of the calenwhen the box on the opposite side. can be removed by detaching the rods A, the object of my invention being to remove a worn-out box from the calender frame without removing the calender-rolls.

I claim- The combination of the removable box with the oiling device.

HERMANN L. BEHRFNS.
